A method is described in which tritium is counted as water vapor in a heated proportional counter filled with methane. Introduction of the sample is rapid and simple, and convection mixing with the counting gas is obtained from the heating system. Good plateaus are obtained with small partial pressures of water vapor at 90 C. The counter is calibrated using a standard tritiated water sample. The system is simple and rugged and gives results reproducible within plus or minus 2% standard deviation.
